@vaporeon_ this was a bit frustrating to track down but what i can tell it's

grocery, from middle english grocerye, an adjectivalization of grocer (wholesaler, one who mans a grocery (that is, a grocery store)), from anglo-norman grōcer, from old french gros (large, thick, fat— modern english gets the sense of “gross” that means large from this word), from latin grossus

@vaporeon_ so i guess etymologically, a grocery store is roughly “a store you get a bunch of shit at once from”

@vaporeon_ but in common usage that normally means “store where you buy purrimarily food and maybe also other useful things”
